There's also a large spectrum of "bad" kids, and a lot of the time the "bad" students educational needs aren't being met, either. For instance, there are, as you said, kids who are violent and disruptive and the answer might not be to expose them to more students but to remove them from the student body entirely and get them into a specialized program focused on trying to improve the emotional problems the kid has.

There are other "bad" students which might not be a problem, but it's clear that the efforts to educate them are a waste[1]:

> In the last four years, France’s son passed three classes, failed 22 and was late or absent 272 days, the teen’s transcript shows. ** > France’s son has a 0.13 GPA, which traditionally places a student near the bottom of their class. But in his case, it put him 62nd out of 120, which would indicate a wider-spread academic performance issue going on at the school.

You can't just drop some good kids into this failing system and expect students like that to suddenly do well.

I think people should reconsider trade schools, including ones that start at relatively young ages. Include an opportunity to earn money at a young age. Just paying teachers to teach kids like that classes that they keep failing doesn't help the kids or anyone else.

There's a stage of puberty boys go through where it would work better to give them a whole schedule of Shop Class/Gym/Work-study, or similar for that year. They're re-learning how to control and move their growth spurt body and re-learning how to think with the suddenly increased Testosterone level.

Tracking folks earlier would also probably help. A lot of my peers growing up worked 4 hours of their school day their senior year, those guys all own homes way before my college bound peers did.

This is exactly the issue that drives folks from "bad schools." The inability of those schools to control disruptive students.

If public schools were permitted to prevent the harms of disruptive students from impacting classroom management by informing parents, "You child is no longer welcome in our classroom, you are required to find someone who will put up with them" and handing them a voucher; then I strongly suspect we would learn that the quality increased and the number of disruptive students went down as parents were forced to deal with the costs those students had imposed on us.

This is an intensely personal choice. I know people who automatically reject public schools because they consider them all low quality. I remember I saw a rude store customer say "They must have went to public school." after an employee made a math error. The devout choose Catholic schools because of values education sometimes even if they have to pay tuition. Some have to enroll their kids in public school because they feel going to a school with a normal cross section of the community is preparation for real life (and especially not a gender segregated school). Some want their kids to attend a racially and economically diverse school even if quality suffers, because their think a good student can achieve in even a mediocre school. Or vice versa they value diversity but not as much as the best schools and those are typically with above average household income and usually <15% or even <10% racial minorities.

> How much do the “good” students help the “bad” students compared to the bad students harming the good students by disrupting classes, bringing violence to the school, or otherwise slowing down learning?

I don't think the parent poster is making a diversity argument here (ie. having "bad" students alongside "good" students enriches the experience for everyone involved). He's more making an argument that a society should engage in redistribution from the "healthy/privileged/lucky/etc" to the "less fortunate ones".

In some cases it is also going to redistribute misfortune as well. Is that fair or desirable?

I'm not sure what gave you the impression that I support putting "bad" students alongside "good" students, which is what I presume you mean by "redistribute misfortune". My last comment is specifically denies this (ie. "having "bad" students alongside "good" students"), and "redistribution" straightforwardly implies redistribution in resources/money.

Giving more money and resources to people who don’t want to take advantage of them in the first place isn’t going to fix the problem.

There are many parents who can afford private school but send their kids to public schools for the heterogeneity.

I do this and do question whether or not it’s the right choice (financially it’s saving me a few million, but that’s just money).
